The North Coast AVA (American Viticultural Area) is one of California's premier wine-growing regions, covering more than three million acres in Napa, Sonoma, Mendocino, and Lake counties, as well as parts of Marin and Solano. Bordered by the Pacific Ocean to the west and San Pablo Bay to the south, the area is composed of rugged coastal ranges, volcanic mountains, gentle rolling hills, deep valleys and wide alluvial plains. With tremendous diversity in soil types and microclimates, the North Coast produces grapes that are deeply influenced by terroir, infusing the wines with character and a unique sense of place that can't be found anywhere else in the world.
